Hi! I am Denis, Assistant Professor at the Department of Computer Science, in the School of Engineering at PUC Chile. I am also adjunct researcher at the Millennium Institute for Research on Fundamentals of Data.
My research interests are Recommender Systems, Intelligent User Interfaces, and Information Visualization and I am currently leading the SocVis Research Lab. If you are interested on these topics and want to work under my supervision as Master or PhD student, send me an e-mail to dparra[at]ing[dot]puc[dot]cl.

March 2019 I am attending the 24th ACM IUI conference in Los Angeles, CA, USA. We are presenting the paper "The Effect of Explanations and Algorithmic Accuracy on Visual Recommender Systems of Artistic Images," where we conduct a user study in order to measure and synthesize the impact of several aspects (algorithm, type of explanation, user expertise) upon different dimensions of the UX with an art recommender systems (perception of relevance, trust, understandability, etc.) [paper]

January 2019 Three of my master students successfully defended their theses: Mar\'ia Fernanda Sep\'ulveda, Vicente Dominguez and Pablo Messina. Kudos for them! Another student, Jorge Schellman, is defending in 2 days, hopefully he does well too.

October 2018 I attended the ACM RecSys 2018 conference in Vancouver, Canada. We presented 2 papers in co-located workshops, one at RecSysKTL by del Río et al. "Do Better ImageNet Models Transfer Better … for Image Recommendation?"[paper][slides], and another one at the IntRS workshop by Dominguez et al. "Towards Explanations for Visual Recommender Systems of Artistic Images" [paper]
